R+W Couplings – Precision, Reliability, Flexibility
For over 30 years, R+W Antriebselemente GmbH has been developing and manufacturing state-of-the-art shaft couplings for precision and industrial drive technology. Headquartered in Germany, R+W has become a global player offering solutions for machinery manufacturing, robotics, automation, medical technology, and many other industries.
Product Categories
• Precision couplings: bellows, elastomer, and miniature versions, torque limiters, disc couplings, and drive shafts – covering a torque range from 0.05 to 25,000 Nm. These couplings are characterized by completely backlash-free operation and a maintenance-free design.
• Industrial couplings: high-torque, robust designs (200 to 2,080,000 Nm) such as gear couplings, disc pack couplings, and flange types – capable of compensating for shaft misalignment and withstanding extreme industrial loads.
Key Advantages
• Backlash-free – for precise torque transmission and excellent positioning accuracy
• Wear-free, long-lasting construction
• Modular and customizable – adaptable designs and sizes tailored to specific requirements
R+W couplings offer a reliable solution for any application where precise torque transmission, durable machine elements, and system efficiency are critical.
